A SAN (Storage Area Network) is a high-speed,
high-bandwidth storage network that logically connects storage to servers.
Of course, the SAN network is only as useful as the types of servers,
storage hardware, connectivity hardware and management software that it
Fibre Channel, an open industry standard,
has emerged as the interconnect technology standard for SAN because of
its suitability for storage networking. SAN topologies (switched fabric
or arbitrated loops) extend the concepts offered by traditional server/storage
connections and deliver more flexibility, availability, performance and
allow integrated management.
Fibre Channel is a relatively new technology.
The standards mentioned above have not yet been uniformly adopted
by the various vendors that are fielding "SAN solutions". As
a result, at the present time there are few SAN solutions that can be
regarded as truly "open".
